Intralesional Steroid Injection for Acne In Korea

Mijan Mijan • 8 August 2026

Introduction

A large, painful acne lesion can become uncomfortable and difficult to manage with ordinary skincare. When a deep inflammatory pimple or acne nodule develops, repeatedly squeezing it may increase inflammation and raise the risk of pigmentation or scarring. In selected cases, a dermatologist may consider an intralesional steroid injection as a targeted treatment.

Intralesional steroid injection for acne involves placing a small amount of corticosteroid medication directly into an appropriate inflammatory lesion. The goal is to reduce localized inflammation and help the lesion flatten. This is different from applying a topical acne cream across the skin because the medication is delivered directly into the selected lesion.

Intralesional steroid injections are available in some dermatology clinics in Korea, including clinics in Seoul and Myeongdong. However, they are not appropriate for every type of acne. Proper patient and lesion selection is important because corticosteroid injections can cause complications when used incorrectly, excessively, or too frequently.

What Is an Intralesional Steroid Injection for Acne?

A Targeted Acne Treatment

An intralesional injection places medication directly into a specific skin lesion.

For selected acne lesions, a corticosteroid may be used to reduce inflammation. Because only a small amount is injected into the lesion, the treatment is localized rather than intended to treat the entire face.

How It Differs From Oral Steroids

An intralesional injection is different from taking corticosteroids by mouth.

The medication is administered directly into a selected lesion under medical supervision. The dermatologist determines whether this localized treatment is appropriate.

Which Acne Lesions May Be Treated?

Large Inflammatory Pimples

A large, swollen, painful acne lesion may sometimes be considered for intralesional treatment.

These lesions can be deeper than ordinary surface pimples and may take longer to resolve.

Acne Nodules and Cysts

Selected nodular or cystic acne lesions may respond to intralesional corticosteroid treatment.

However, the term "cystic acne" is often used broadly online. A dermatologist should examine the lesion rather than assuming that every large pimple is suitable for injection.

Which Acne Lesions Usually Do Not Need Steroid Injection?

Blackheads

Blackheads are clogged pores rather than large inflammatory lesions.

They are generally managed with appropriate acne medication, skincare, or professional extraction when appropriate.

Small Whiteheads

Small whiteheads typically do not require an intralesional steroid injection.

A dermatologist may recommend other treatments depending on the overall acne pattern.

Mild Surface Pimples

For small, uncomplicated pimples, a targeted steroid injection may provide little benefit compared with simpler acne management.

How Does an Intralesional Steroid Injection Work?

Reducing Local Inflammation

Corticosteroids have anti-inflammatory effects.

When injected into a suitable inflammatory acne lesion, they can reduce localized inflammation and swelling.

Helping a Deep Lesion Flatten

As inflammation decreases, the treated lesion may become less swollen and painful.

The speed and degree of improvement vary according to the lesion and individual response.

It Does Not Cure Underlying Acne

An intralesional steroid injection treats a particular lesion.

It does not correct every factor contributing to acne, such as excess sebum, clogged pores, hormonal influences, or acne-prone skin.

Patients with recurring acne may need a broader long-term treatment plan.

What Happens During Steroid Injection for Acne In Korea?

Step 1: Dermatological Assessment

The dermatologist first examines the lesion.

They may consider:

  • Size
  • Depth
  • Inflammation
  • Location
  • Duration
  • Previous treatment
  • Skin condition

This helps determine whether an injection is appropriate.

Step 2: Skin Preparation

The treatment area is cleaned and prepared before the injection.

The provider should follow appropriate infection-control procedures.

Step 3: Localized Injection

A small amount of corticosteroid medication is injected directly into the selected lesion.

The procedure is generally brief.

Step 4: Aftercare

The clinic may provide instructions regarding cleansing, skincare, makeup, and touching the treated area.

Follow the provider's specific recommendations.

Is an Intralesional Steroid Injection Painful?

Brief Pinching or Stinging

Patients may feel a short pinch or sting when the needle enters the skin.

The level of discomfort varies depending on the lesion and individual sensitivity.

Deep Lesions May Be More Sensitive

Inflamed acne can already be tender before treatment.

Tell the provider if the area is particularly painful or sensitive.

How Quickly Can a Steroid Injection Reduce Acne Inflammation?

Potentially Rapid Reduction

One reason dermatologists may consider intralesional corticosteroid treatment for selected lesions is that inflammation can decrease relatively quickly.

The treated lesion may become:

  • Less swollen
  • Less painful
  • Flatter
  • Less visibly inflamed

However, the exact response varies.

Results Are Not Guaranteed

Not every lesion responds in the same way.

Some lesions may require additional acne management rather than another injection.

Intralesional Steroid Injection vs Popping a Pimple

Why Squeezing Can Be Harmful

Trying to force a deep pimple to the surface can damage surrounding tissue.

This may increase:

  • Inflammation
  • Redness
  • Skin trauma
  • Post-inflammatory pigmentation
  • Scarring risk
Professional Assessment Is Different

A dermatologist can determine whether the lesion should be injected, treated with another medical approach, or simply left to resolve.

Potential Benefits of Intralesional Steroid Injection

Targeted Treatment

The injection is directed at a specific inflammatory lesion rather than treating unaffected areas.

Potential Reduction in Pain

As inflammation decreases, tenderness may also improve.

Convenient for Selected Situations

Because the procedure is generally brief, it may be considered when a patient has a particularly troublesome lesion.

Risks and Side Effects of Steroid Injections for Acne

Skin Atrophy

One of the important potential complications is localized skin thinning or atrophy.

This can sometimes produce a visible depression in the treated area.

Indentation

A small depression may develop if the corticosteroid affects the local tissue excessively.

This is one reason careful dosing and appropriate injection technique matter.

Pigmentation Changes

Temporary or persistent changes in skin pigmentation may occur.

Patients who are prone to post-inflammatory pigmentation should discuss this concern with their dermatologist.

Visible Small Blood Vessels

Localized vascular changes can occur in some cases.

The risk depends on factors including medication, concentration, technique, and individual skin characteristics.

Infection

Any injection can carry a risk of infection.

Appropriate skin preparation and medical technique are important.

How Often Can You Receive Intralesional Steroid Injections?

Not a Routine Acne Treatment

Intralesional steroid injections are generally intended for selected lesions rather than routine treatment of every acne breakout.

Repeated injections into the same area may increase the risk of local complications.

Underlying Acne Should Be Managed

If you frequently develop large nodules or cysts, treating individual lesions without addressing the overall acne pattern may not provide adequate long-term control.

A dermatologist may recommend a broader acne management strategy.

Who May Be a Good Candidate?

Patients With Selected Large Inflammatory Lesions

A dermatologist may consider the procedure when a lesion is:

  • Large
  • Deep
  • Painful
  • Significantly inflamed
  • Suitable for localized treatment
Patients Who Need Targeted Treatment

Some patients seek treatment for one particularly prominent lesion while managing the rest of their acne through other methods.

The dermatologist should determine whether injection is appropriate.

Who Should Exercise Particular Caution?

People With a History of Skin Atrophy

If you have previously experienced indentation or skin thinning after corticosteroid treatment, tell the dermatologist before injection.

Patients With Pigmentation Concerns

People who develop dark marks easily may need individualized consideration.

People Taking Certain Medications

Always provide a complete medication history, including prescription drugs, supplements, and topical treatments.

Intralesional Steroid Injection for International Patients In Korea

Why Tourists May Consider It

International visitors may develop an unusually large inflammatory pimple during a trip to Korea.

A quick dermatological assessment can determine whether a localized injection is appropriate.

Consider Your Departure Date

Although the procedure itself is usually brief, the treated area can experience temporary changes.

Tell the clinic when you plan to leave Korea so the provider can discuss expected recovery and follow-up.

Do Not Schedule Based Only on an Event

If you have an important event, photo session, or business meeting, ask about possible redness or other temporary reactions before treatment.

Aftercare Following an Acne Steroid Injection

Keep the Area Clean

Follow the clinic's cleansing instructions after treatment.

Avoid unnecessary touching.

Avoid Picking the Lesion

Do not squeeze the treated area even if some swelling remains.

Manipulation can increase irritation and skin trauma.

Follow Medication Instructions

If the dermatologist recommends topical or other acne medication, use it according to the instructions provided.

Can Steroid Injection Prevent Acne Scars?

Controlling Inflammation May Be Helpful

Deep inflammatory acne can increase the risk of permanent scarring.

Reducing significant inflammation may be part of managing an individual lesion.

However, an injection cannot guarantee that a scar will not develop.

Existing Scars Require Different Treatment

Intralesional steroid injections do not remove established rolling, boxcar, or ice-pick acne scars.

Once active acne is under control, a separate acne scar assessment may be appropriate.

How Much Does Intralesional Steroid Injection Cost In Korea?

Factors Affecting Price

The cost may depend on:

  • Number of lesions
  • Medication used
  • Clinic
  • Consultation
  • Treatment area
  • Additional acne treatment

Some clinics may charge according to the number of treated lesions, while others may incorporate injections into an acne treatment program.

Ask About the Complete Price

Before treatment, confirm whether the quoted cost includes the consultation, injection, medication, and follow-up.

How to Choose an Acne Clinic In Korea

Look for Proper Medical Assessment

A qualified provider should examine the lesion before recommending an injection.

A large bump should not automatically be treated as acne without appropriate assessment.

Ask About Risks

Before treatment, ask about the potential for:

  • Skin thinning
  • Indentation
  • Pigmentation changes
  • Visible blood vessels
  • Infection

Understanding these risks is particularly important when treating the face.

Avoid Clinics That Promise Perfect Results

No acne treatment can guarantee permanent clearance or complete prevention of scarring.

A trustworthy consultation should explain realistic benefits and limitations.

Conclusion

Intralesional steroid injection for acne can be a useful targeted option for selected large, painful, inflammatory acne lesions. By delivering a small amount of corticosteroid directly into the lesion, the treatment may reduce localized inflammation and help a suitable pimple flatten more quickly.

However, this is not a routine treatment for every type of acne. Blackheads, whiteheads, small pimples, and recurring acne generally require different management. Repeated or inappropriate steroid injections can also cause complications such as skin thinning, indentation, and pigmentation changes.

For patients considering intralesional steroid injection in Korea, a dermatologist should first assess the individual lesion and review the patient's medical history. International visitors should also discuss their travel schedule and expected recovery before treatment. When appropriately selected and professionally performed, localized acne injection can be one component of a broader acne management plan.
